Discuss always links the Clearnet Forum only

I dont know if this is possible, probably Discover has been set up with all the Clearnet URLs and the Onion is only on top of that, but it would be great to directly have onion addresses in the Mails?

Don’t know if this is necessary, as the rest of the site uses onion only, which is great (many other Clearnet/onion Sites dont have that and always link to Clearnet)
